I know Firefox can sync your bookmarks across multiple computers but I don't really trust leaving them all in there so I created an extremely simple link manager script a while ago that I use religiously and have released for download (free) here:

Looks kind of like overkill at first but it's really very usefull IMO
Edit: whoops this thread is old as fuck lol, found it searching for something.
